Description

  The present invention relates to a deodorant composition suitable for deodorizing malodors in a living environment. In particular, the present invention relates to a deodorant composition comprising a carboxyl group-containing gelled polymer and a metal deodorant.

  There are various compounds in the living environment that give off an unpleasant odor to the surroundings or even detrimental to human health. For example, ammonia, amines, hydrogen sulfide, mercaptans, lower fatty acids, aldehydes, and the like are typical compounds that cause odors in kitchens, restrooms, basements, cars, and the like. Many types of deodorizers have been developed to deodorize or absorb these malodours. Commercially available deodorizers typically mask malodors by emitting fragrances, or physically absorb and / or chemically react with malodorous substances. Substances usually used as an absorbent include activated carbon, zeolites, cyclodextrins, bentonites and the like. Substances commonly used to react with malodorous substances include chlorine dioxide, hypochloride, ozone, polymers containing functional groups, and the like. These substances decompose malodorous compounds by oxidation, reduction, or neutralization reactions.

  Metals or metal compounds have been suggested for use in deodorant products. Typically, deodorant products are provided and used in packages containing multiple individual chunks of deodorant compositions that include deodorant actives. The inventors of the present invention, regarding such a deodorant product, in addition to the concentration of the metal or metal compound contained in the deodorant composition, the shape and surface area of the individual masses of the deodorant composition Has also been found to affect the deodorizing performance of the deodorant product. Therefore, there is still a need for an optimal shape and surface area of the deodorant composition. In addition, for gel deodorant compositions comprising a metal or metal compound, the concentration of metal or metal compound normally required in the deodorant composition gives the gel an unpleasant color and / or poor color integrity As such, the formulator may feel a dilemma regarding blending a metal or metal compound into the gel deodorant composition. For example, if the copper compound is formulated at a high concentration in the gel deodorant composition, the gel may have a dark blue color that is not of interest to consumers. Similarly, when a nickel compound, iron compound, cobalt compound, or platinum compound is blended at a high concentration in the gel deodorant composition, the color of the gel may become dark, and the zinc oxide is high in the gel. When used at a concentration, the gel has a whitish color and may be in an undesirable opaque state. On the other hand, the silver compound may change its color when included in the gel deodorant composition at a high concentration and when it comes into contact with air during use. Therefore, there is still a need for a gel or metal compound-containing gel deodorant composition that is effective in deodorizing odors in the living environment, particularly in the bathroom, and at the same time has an attractive color and improved color integrity. ing.

Have been found to have complete color integrity.

As noted above, when a metal or metal compound is incorporated into a gel deodorant composition, typically the concentration required to provide sufficient deodorization performance is the color that the gel deodorant composition is undesirable in. And / or have poor color integrity. Extensive research has been done to address this problem and in three-dimensional shapes selected from block shapes, spheres, ovals, cones, and cylinders with a surface area of about 24 mm ² to about 2400 mm ² . Gel deodorant compositions can provide satisfactory deodorization performance with relatively low concentrations of metals or metal compounds, and are therefore associated with high metal or metal compound content in the gel deodorant composition. It has now been found that problems such as unattractive colors and poor color integrity are solved. Without being bound by theory, a cubic selected from a block shape, a sphere, an ellipse, a cone, and a cylinder having a surface area of about 24 mm ² to about 2400 mm ² , or about 150 mm ² to about 600 mm ² The original shape is believed to increase the contact of the metal or metal compound with malodorous compounds. Furthermore, in the deodorant product, the individual masses of the deodorant composition having a three-dimensional shape in the above size range do not clog each other, and the space between the individual masses facilitates air flow. It can be considered. The result is a gel deodorant product that has attractive colors, improved color integrity, and consumer-recognized deodorization performance.
